Trendsetter Electronics offers X-Rel Semiconductor's XTR30014-D, a high temperature PWM controller that comes in a ceramic DIP24 package. This device has a 50V supply voltage and operates from -60C to +230C.

XTR30010 is a family of small footprint PWM controllers de-signed for extreme reliability and high temperature applications such as DC/DC converters and PWM control. Being able to op-erate from input voltages as high as 50V, XTR30010 PWM con-trollers can run at frequencies as high as 800kHz, allowing the use of small footprint and low-cost external passive components. Functionality features include internal oscillator and voltage ref-erence, programmable soft-start, voltage tracking, synchronization capability, over-current protection and power-good flag. Special design techniques were used to allow the XTR30010 parts to offer a precise, robust and reliable operation in critical applications. Full functionality is guaranteed from -60�C to +230�C, though operation well below and above this temperature range is achieved. Parts from the XTR30010 family have all functional features to operate in buck, boost, buck-boost, fly back and push-pull modes. Standard packaging options range from full-featured 24-lead packages to small footprint 8-lead packages. XTR30010 family parts have been designed to reduce system cost and ease adoption by reducing the learning curve and providing smart and easy to use features. Parts from the XTR30010 family are available in ruggedized SMT and thru-hole packages. Parts are also available as bare dies.
